挪威杉木 的英文怎麼說
中文拼音 [nuówēishāmù]
挪威杉木
英文
white deal-
Microarray analysis and plantlets regeneration of the transgenic norway spruce ( picea abies ) for low - content lignin norway spruce is one of the two most important forest tree species in europe and the preferred species for pulp manufacture
挪威雲杉( piceaabies )是歐洲的主要用材樹種,也是重要的造紙原料樹種。其木材的主要成分除纖維素外,還有15 - 36的木質素。Recent developments in molecular biotechnology are making this possible. in the work described here, three transgenic sublines of embryogenic norway spruce calli : a78 - 3, a78 - 4 and a78 - 5 were studied
隨著分子生物學技術的發展,通過轉基因技術有目的地培育出木質素含量低的挪威雲杉新品種就成為可能。They contained an antisense constructed for the spruce gene encoding ccr ( cinnamoyl alcohol dehydrogenase ), an enzyme of monolignol synthesis. the antisense rna method is a technique for reducing the expression of a resident target gene. the transgenic sublines were produced by particle bombardment at the dept of forest genetics, swedish university of agricultural sciences
本項目研究的目的就是採用瑞典農業大學構建的反義ccr基因轉導的挪威雲杉細胞愈傷組織,通過誘導產生再生植株,並檢測證實該基因是否表達及其它相關基因的表達狀況,為培育出低木質素的轉基因挪威雲杉新品種奠定物質和理論基礎。The decrease of lignin has to be achieved without interfering the stability of the tree, the efficiency of water and nutrient transport, and its resistance to pathogen
與絕大多數林木一樣,挪威雲杉的常規育種周期長達25年以上,而且常規選擇育種容易受到自然條件和資源的限制。An attractive objective in tree breeding is therefore to reduce the content of lignin
為此,開展木質素含量低的挪威雲杉新品種的選育就成為一個迫切需要解決的問題。分享友人
